If that money is burning a hole in your pocket I'd suggest a different direction. I have a couple of Provari's, and an evic, ever since I got a bottom feeder I haven't touched them. I have 2 Reo Grands with reomizer 2 rba's, i have been using microcoils and I absolutely love it. Same great taste of dripping on an rba, but with the convince of a tank. They are a mechanical, one year warrenty, andRob sells rebuild kits if anything does go wrong (or you can send back in to be fixed). Check out http://www.e-cigarette-forum.com/forum/reos-mods/
